What is the difference between 6 M H2SO4 and 0.1 M H2SO4?

Answer 1

The first solution is more concentrated because it contains 6 moles of H2SO4 per one liter of solution. The second solution is less concentrated because it contains 0.1 moles of H2SO4 in one liter. In equal amounts of each example, the first would have more H2SO4.

Answer 2

The main difference is the concentration of sulfuric acid in the solution. A 6 M solution of H2SO4 is more concentrated than a 0.1 M solution. This means that the 6 M solution has a higher amount of sulfuric acid dissolved in the solvent compared to the 0.1 M solution.
